A.P. Bio Season 3

2020 8 Episodes Comedy ⭐ 7/10

Right now you can watch A.P. Bio Season 3 on and — and it is funnier than its reputation suggests. A single, tightly-focused season means there is plenty to get through without ever feeling padded. A 7/10 rating says what the writing already makes obvious: this one works. Glenn Howerton leads a cast with real comic timing. Put it on tonight and see for yourself.

There is a reason A.P. Bio Season 3 keeps coming up in conversation. A.P. Bio Season 3 does what great comedies rarely manage — it is actually funny, consistently, across the whole run. Season 3 of A.P. Bio marked the show’s transition from NBC to the streaming platform Peacock. This shift allowed the series to become more experimental, lean into its absurdist comedy, and focus less on Jack Griffin's (Glenn Howerton) desire to leave Toledo and more on his bizarre integration into Whitlock High. Glenn Howerton and Patton Oswalt lead a cast that brings real weight to the material. It was aired in 2020. The real test of any comedy is whether it is still funny once you know all the jokes, and A.P. Bio Season 3 holds up on rewatch in a way that separates it from one-off curiosities. It delivers reliably on what it promises, which is more than most of its competition manages.

Comedy fans looking for a reliably funny watch will find it in A.P. Bio Season 3. It stands on its own even without an obvious comparison point. Short enough to finish in a weekend, substantial enough to feel satisfying. Glenn Howerton's comic timing carries it through its weaker moments. The kind of comedy you recommend to someone who claims they do not watch much.
